FRANK NEDERMAN, OF CHICAGO, ILLINOIS.

CUSPIDOR.

To all whom it may concern:

Be it known that I, FRANK NEDERMAN, a citizen of the United States, residing at 904 North Kimball avenue, in the city of Ohicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Ouspidors, of which the following is a specification.

rlhe object of my invention is to so cone struct the upper and lower members that they can be Iioined together, locked and unlocked by a slight turn of the parts in opposite directions, and when separated all parts of each member be visible, easily cleaned and a perfect sanitary condition be thereby provided for.

The manner in which I accomplish my object is described in the following specification, and illustrated in the accompanying drawings in which:

Figure 1 is a vertical central sectional view, the top and bottom members being separated. Fig. 2 is a horizontal sectional view on the line 2-2 Fig. 3. Fig. 3 is the same as Fig. l, except that the two members are in the closed position ready to be locked together by rotation of the parts. a central vertical section showing the parts in the locked position.

In the drawings, A indicates the lower member as a whole, the base B is adapted in shape and weight to maintain the cuspidor in a vertical position. Around the interior of the upper part O are two flange parts I) the ends E being s aced from each other as shown in Fig. 2. t the center of the length of each of these ilange parts is a curved swell F. The upper member G is smaller and lighter than the lower member. The lower part A, is adapted in size to correspond with the top part O of the lower member, and is provided with two lugs I. These lugs are adapted to be inserted into the lower member through the space J, between the ends E of the flanges D as shown in section in Fig. 2. In each of these lugs is a channel K adapted to admit the flange parts D. The central part of each of these channels is a curved swell L corresponding in form to the swells F of the flange parts D as shown by the dotted lines in Fig. 4.

When the parts are constructed as described, to secure the members together the Specification of Letters Patent.

Application led March 2, 1908.

parts are placed in the relative positions shown in Fig. l; the lugs I are then inserted in the spaces J in the positions shown in Figs. 2 and 3. The members A and G are then turned in opposite directio-.s till the swells F and Il are in contact as sgon'n by he dotted lines in Fig. 4 in which position the parts O and l-I of the lower and upper members are drawn close together and the two members are locked together ready for use. To separate the members for cleaning, the parts are turned again in opposite direction and the lugs slipped out of the spaces J. The interiors of the separate parts are then accessible for cleaning and inspection, and are thus adapted to be kept in a sanitary condition which is the central object of my invention.

The material used is preferably of cheap glazed or enameled material so that they may be desirable for the most general and common use where cleanliness is most necessary and usually least observed.

What I claim and desire to secure by Letters Patent is:

l. In an article of the kind described, the combination consisting of a base part having interior marginal flanges the opposite ends of said llanges being spaced from each other and the central part of each flange having a downward curved swell; a top part having lugs adapted to be inserted in said base part in spaces between the ends of the flanges in said part, said lugs having exterior channels adapted to admit said flanges and to permit said top part to rest on said base part, and said parts to be rotated one upon the other and to be locked together by the engagement of said lugs withv the curved swell on each of said flanges as described.

2. In an article of the kind described, the combination with a base part having two semi-circular'flanges 5 the ends thereof s aced from each other, the center of each ange being curved downward and thereby enlarged vertically; of a top part adapted to be superimposed on said base, the circumference of said parts being coincident, said top part having two lugs insertible in said base part between the ends of said flanges, each of said lugs having an exterior channel adapted to admit said flanges and to permit said part to be rotated on said base and to engage said curved arts of said flanges and thereby lock said Ease and top parts together as described.

3. A cuspidor consisting of a circular base, 5 having upper marginal flanges thickened vertically in the center; and a circular top adapted to fit on said base, having lugs insertible in said base adapted to admit said lianges and to permit said top to be partly rotated on said base and to engage the thick 10 part of said flanges and thereby lock said top and base together as described.
